Can you try to switch off the application preference to show warnings as dialogs:Edit - Application Preferences - Widgets - Command Line - [ ] Show warnings as dialog (make sure that option is NOT checked).

This option might cause problems with warnings produced when drawings are loaded since you might have to click away a lot of dialogs. I'll look into options to fix this problem for the next release.

Simplest way was to just remember the last message and only show the current one, if different from the last one. Probably increment a counter for each occurence. This may still swamp the user though if eg. two different messages alternate.

Another way, store any messages into an object with a counter and only ever show the popup with a liste of messages in the end of an action.
